Fastener is a kind of mechanical part widely used for fastening connection. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization and versatility. Therefore, some people also call a class of fasteners in the standard as standard fasteners, or standard fasteners for short.
What are the main uses of fasteners:
Fasteners are mainly used in the fields of energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic pressure, etc. There are various fasteners on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies. Fasteners are also known as the most widely used mechanical foundation parts.
Fastener introduction:
Fasteners include: bolts, studs, screws, nuts, washers and pins. Fasteners made of stainless steel, aluminum alloy and titanium alloy will lock or bite. The fasteners themselves have corrosion resistance and form a thin oxide layer on the metal surface to prevent further corrosion when the surface is damaged.
When the stainless steel fastener is locked, the pressure and heat generated between the teeth will destroy the oxide layer, causing the metal thread to be blocked or cut off, thus jamming. When this happens, stainless steel fasteners are fully locked and can never be removed or locked. This blocking shearing bonding locking sequence usually takes place within a few seconds. Therefore, it is necessary to correctly understand such fasteners when using them, so that this phenomenon can be prevented.
